Is Your Dishwasher Making Strange Noises?
Dishwashers should run quietly. If yours has started making unusual sounds, here’s how to figure out what might be going on.
Normal Dishwasher Noises
- Water Swishing or Hissing:
- Normal during spray arm rotation or draining.
- Light Humming:
- Often from the pump or fan.
- Beeping at End of Cycle:
- Some models alert you when finished.
- First-Time Use Squeal:
- Happens in new machines or those not used in a while. Add a bit of water to the tub before running.
Sounds That Need Attention
- Banging or Thumping
- Caused by the spray arm hitting a large dish or utensil.
- Check for items hanging below racks.
- Reorganize dishes to allow free rotation.
- Loud Grinding
- Could be debris in the drain impeller or grinder.
- Stop the cycle and check for stuck food, glass, or other items.
- Remove anything you find before restarting.
- Unusual Humming or Buzzing
- May indicate a failing motor or clogged drain.
- If the motor sounds louder than normal, schedule a service visit.
- Beeping During the Cycle
- Could mean the door was opened mid-cycle or there’s an error.
- Check for flashing lights and consult the manual.
- Knocking from the Pipes
- Known as water hammer.
- Happens when water flow suddenly changes.
- May require a plumber to resolve.
What You Can Do
- Always unplug the appliance before inspecting internal parts.
- Clear the spray arms and filter of debris.
- Make sure nothing is blocking the door or latch.
- Run an empty cycle and listen closely.
